    public class RowTransformation<TInput, TOutput> : DataFlowTransformation<TInput, TOutput>, ILoggableTask, IDataFlowLogging, IDataFlowTransformation<TInput, TOutput>, IDataFlowSource<TOutput>, IDataFlowSource, IDataFlowDestination<TInput>, IDataFlowDestination, IDataFlowComponent
Type Parameters
NameDescription
TInput

The type of ingoing data.

TOutput

The type of outgoing data.

Examples
RowTransformation<InputType, OutputType> trans = new RowTransformation<InputType, OutputType>(
row => {
    return new OutputType() { Value = row.Value + 1 };
});

Constructors

Fields

WasInitActionInvoked

Declaration
    protected bool WasInitActionInvoked
Field Value
TypeDescription
bool

Properties

InitAction

The init action is executed shortly before the first data row is processed.

Declaration
    public Action InitAction { get; set; }
Property Value
TypeDescription
System.Action

SourceBlock

SourceBlock from the underlying TPL.Dataflow which is used as output buffer for the component.

Declaration
    public override ISourceBlock<TOutput> SourceBlock { get; }
Property Value
TypeDescription
System.Threading.Tasks.Dataflow.ISourceBlock<TOutput><TOutput>
Overrides
ETLBox.DataFlow.DataFlowSource<TOutput>.SourceBlock

TargetBlock

TargetBlock from the underlying TPL.Dataflow which is used as input buffer for the component.

Declaration
    public override ITargetBlock<TInput> TargetBlock { get; }
Property Value
TypeDescription
System.Threading.Tasks.Dataflow.ITargetBlock<TInput><TInput>
Overrides
ETLBox.DataFlow.DataFlowTransformation<TInput, TOutput>.TargetBlock

TaskName

A name to identify the task or component. Every component or task comes with a default name that can be overwritten.

Declaration
    public override string TaskName { get; set; }
Property Value
TypeDescription
string
Overrides

TransformationFunc

Each ingoing row will be transformed using this function.

Declaration
    public Func<TInput, TOutput> TransformationFunc { get; set; }
Property Value
TypeDescription
System.Func<T, TResult><TInput, TOutput>
